ELECTRIC VEHICLE.

SPECIFICATION forming part of Letters Patent No. 636,964, dated November 14, 1899.

Application filed August 5, 1899. Serial No. 726,278. (No model.)

To aZZ whom it may concern.-

Be it known that I, THEODORE B. ENTZ, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Electric Vehicles, of which the following is a specification.

The object of the present invention is to provide an electric carriage in which the occupants may ride comfortably and without being subjected to undue shocks and jars and in which they are relieved from the heavy running feeling which is one of the disadvantagieous features of electrically-propelled vehi- 0 es.

To this and other ends my invention comprises the improvements hereinafter described and claimed.

The nature, characteristic features, and scope of the invention will be more fully understood from the folloWin g description,taken in connection with the accompanying drawing, forming part hereof, and in which is illustrated an electric vehicle embodying features of my invention.

In the drawing, 1 is a truck comprising suitable wheels, axles, and reaches or perches, or both. This truck may advantageously carry the motor or motors and be provided with steering-gear.

2 is a battery-box or box capable of contain ing the necessary cells or other means for furnishing power. Between the truck 1 and the box 2 are interposed springs 3. Since the contents of the box are usually quite heavy, it follows that the springs 3 should be designed with reference to such weight, and they therefore are quite stiff and are usually under con siderable compression, so that they are not well suited to alford comfort to any one who should ride upon them.

4: is a carriage-body which is complete in itself and is provided with seats and with ap= propriate provisions for the feet of the riders. Between the carriage-body 4 and the box 2 are interposed springs 5. These springs 5 insure comfort to the occupants of the vehicle,- and they can be properly constructed and designed for the accomplishment of that purpose, because they do not have any other work to do.

In the described construction the springs 3 have but one duty to perform-namely, to properly carry the box 2 and its contentsand this duty they can efliciently perform, whereas if they were intended to afford comfort to the occupants they could not be designed so as to accomplish the additional duty. In fact, where one set of springs carries the contents of the box and also the passengers it is found that every once in a while the passengers are subjected to excessive shocks, and at all times they are subjected to the annoyance of the sensation of weight and the heavy running that is incident thereto. By the described arrangement the springs 5 are suited to take care of the Weight of the passengers and of the body 4. only, and there fore they correct the feeling of Weight and also prevent the occurrence in the body of such shocks as have been referred to. Besides this, the desired construction permits of considerable beauty in design and also of the use of several different types of carriagebodies in connection with one truck, box, and other accessories. This is a desirable feature, because the seasons of the year vary. In the matter of the removal and renewal of the cells or contents of the box 2 the described construction also presents advantages, because if the box constituted part of the carriage-body during that operation the carriagebody would be likely to be scratched and marred. Moreover, in the case of storage batteries such fumes or gases as arise therefrom cannot possibly reach the occupants of the vehicle, because the box is well ventilated, whereas if it constituted part of the carriagebody such fumes would be given off in the carriage-body and are likely to cause annoy-' jects of my invention, what I claim as new, posed between the body and the battery-box,

and desire to secure by Letters Patent, is substantially as described. 10
